@Chris350Probably better off buying a tm aftermarket for the we/aw glocks. I know the guarder lightweight bbu works well in we g17s.
Im going to test different materials tomorrow like tpu and carbon fibre as pla will eventually snap.
If you have a specific request, I can potentially model one for you at a cost. It's just that the cz75 bbu doesnt take much stress. A glock might be a different story.
